Abstract
Incremental housing is a gradual construction of homes by the residents over a period of time, particularly in developing countries. The majority of these houses have contributed to the creation of informal settlements, due to non-compliance with Physical Planning Standards (PPS). The existing literature on incremental housing has focused more on financing and tenure insecurity, with little attention paid to compliance with PPS. This study, therefore, examined incremental housing compliance with PPS in the sub-urban Local Government Area of Ibadan, Nigeria. The concept of ‘Survival Strategy’ was used for the study. Survey research design was adopted, and mixed-method sampling strategy was used in administering questionnaires to 1,038 occupiers of incremental buildings from 4,152 in 12 neighbourhoods out of 124 identified by Oyo State Ministry of Lands, Housing, and Urban Development (OSMLHUD). Data were analysed using descriptive statistics and logistic regression at 0.05, while qualitative data were content analysed. The study reveals that 71.1% of the respondents have resided in their houses between 11 and 30 years, while those who have completed one room, two rooms and three rooms constituted 57.4%, 28.1% and 14.5% respectively. 73% of the respondents did not have ABP. Observed stages of development were core (56.1%), expanded (22.3%), and consolidated (21.6%). Houses with pit toilet/latrine, unplastered walls and uncompleted roofs were 84.3%, 62.5% and 52.4% respectively while 72.1% lack functional windows. About 89.5% of the buildings were situated <6m from the PL, 36.4% <10m from EHV, and 18.7% <15m from streamline, while 85.2% did not have parking facility. Hypothesis test discovered that obtaining ABP is a function of age (OR=1.05, CI: 1.02-1.08), income (OR=1.11, CI: 1.07-1.15), education (OR=1.22, CI: 1.15-1.30), and awareness (OR=1.6, CI: 1.45-1.88). Challenges for enforcing compliance with PPS include limited funding, insufficient personnel, and inadequate equipment. Tenure insecurity, poor awareness, and high cost of documentation were hindrances to obtaining BPA. Therefore, awareness of planning permit and compliance are necessary.
